Bronx District Attorney Darcel D. Clark today announced that a former Rikers Island inmate has been indicted for Attempted Aggravated Assault on a Peace Officer and related charges for slashing a New York City Department of Correction Officer in the jail.

District Attorney Clark said, “The defendant allegedly sneaked out of his cell after lock-in time, grabbed the Officer by the neck and slashed him with a sharp object, causing cuts to the Officer’s neck, ear and two fingers. Such unprovoked brutality against someone performing their job will not be tolerated.”

District Attorney Clark said the defendant, Gerren Delvin, 34, of Queens, was indicted on Attempted Aggravated Assault on a Peace Officer, two counts of Attempted Assault in the first-degree, two counts of second-degree Assault, third degree Assault, second-degree Obstructing Governmental Administration, fourth-degree Criminal Possession of a Weapon and first-degree and second-degree Promoting Prison Contraband. He was arraigned today before Bronx Supreme Court Justice George Villegas. He is due back in court on April 29, 2020.

According to the investigation, on January 9, 2020, in the Anna M. Kross Center, the defendant manipulated his cell so that he would be able to exit his cell after lock-in. As the Correction Officer was taking a count of the inmates during the night, the defendant allegedly approached the Officer and without provocation, grabbed the Officer by the neck and made several swiping motions on the Officer’s neck with a sharp object.

The defendant then allegedly chased the Officer into the dayroom of the facility making swiping motions with the sharp object, inflicting cuts to the Officer’s neck, ear and thumb, and a cut to his middle finger that required stitches. The defendant is currently serving a prison sentence for firearms trafficking.

The case is being prosecuted by Assistant District Attorney Chantelle Williams of the Rikers Island Prosecution Bureau, under the supervision of Francis T. Alberts, Chief of the Rikers Island Prosecution Bureau, and under the overall supervision of Tarek Rahman, Deputy Chief of the Investigations Division. District Attorney Clark thanked her Detective Investigator Timothy Gernon, and Trial Preparation Assistant Niurka Crespo of the Rikers Island Prosecution Bureau for their assistance.

District Attorney Clark thanked Investigators Scott Frank and Daniel Monaco of the DOC Correction Intelligence Bureau for their assistance in the investigation.

An indictment is an accusatory instrument and not proof of a defendant’s guilt.
